Renata ganó una rifa y se le entregaron 7832 pesos. Ella decidió repartirlos de la siguiente manera: a su mamá 3/8 del total, a
gogolik [260]

Answer:

A su mamá

= 2937 pesos

A su hermano

= 1566.4 pesos

El resto para ella

= 3328.6 pesos

Step-by-step explanation:

El número total de pesos que cada uno consiguió se calcula como:

Su madre

= 3/8 del total

= 3/8 × 7832

= 2937 pesos

Su hermano

= 1/5 del total

= 1/5 × 7832

= 1566.4 pesos

Sí misma

= El resto

= 7832 - (2937 + 1566,4)

= 7832 - 4503.4

= 3328.6 pesos

Trucks that travel on highways have to stop at various locations to be weighed and inspected for safe brakes and light systems.
IrinaVladis [17]

Answer:

The reuired probability is 0.756

Step-by-step explanation:

Let the number of trucks be 'N'

1) Trucks on interstate highway N'= 76% of N =0.76N

2) Truck on intra-state highway N''= 24% of N = 0.24N

i) Number of trucks flagged on intrastate highway  = 3.4% of N'' = \frac{3.4}{100}\times 0.24N=0.00816N

ii)  Number of trucks flagged on interstate highway  = 0.7% of N' = \frac{0.7}{100}\times 0.76N=0.00532N

Part a)

The probability that the truck is an interstate truck and is not flagged for safety is P(E)=P_{1}\times (1-P_{2})

where

P_{1} is the probability that the truck chosen is on interstate

P_{2} is the probability that the truck chosen on interstate is flagged

\therefore P(E)=0.76\times (1-0.00532)=0.756

A partial factorization of x2-3x-10 is modeled with algebra tiles
Allushta [10]

X² - 3x - 10


x² = x * x

10 can be factored:

1 x 10 ⇒⇒⇒ difference between factors = 9

2 x 5   ⇒⇒⇒ difference between factors = 3  ⇒ (The correct pair)


(x-5)(x+2) = x(x+2) - 5(x+2)

                = x² + 2x - 5x - 10

                = x² - 3x - 10



∴ x - 5 = 0  ⇒⇒⇒ x = 5

  x + 2 = 0  ⇒⇒⇒ x = -2
